Gearbox Question Grinding Me

Isn't Honda's DCT exactly that?

No DCT is (Duel Clutch Transmission) which is more a semi automatic system, which may or may not have duel countershafts in the box, seems a bit like the old semi automatic bus boxes to me but electronic control.

Duel countershafts are in the box and transfer drive from primary to main shaft.

As far as Im aware its not something currently adopted in any production motorcycle (I could be wrong though). I know they have started using them in some racing applications (some BRISCa F2's run them, as do some drag machines).

I think they are more important in applications where high torque capabilities are needed though - hence their wider use in commercial lorry applications?

I couldn't remember the reasoning behind the twin counter-shaft idea, but knew that torque was involved,.
I just wondered if there was a weight saving advantage that may have been used on more high performance engines.
But I guess that with the need to stop the back wheel spinning up and the introduction of traction control, there isn't so much power being fed through the box suddenly.
